Where \(D\)  computes the cosine distance, and \(i\)  indexes over the spatial indexes of \(T\)  and \(\Phi (O)\)  (which are both a quarter of the original resolution of \(C\) ). To further improve the 'realism' of our results and encourage better capturing the target style we also employ the adversarial patch co-occurrence loss proposed by Park et al. [1]}:
\(\mathcal {L}_{adv}= -\log \mathcal {D}(\Theta ^{(4)}(S), \Theta ^{(1)}(O))\)
